SEATTLE (AP) -- Despite a slight increase in Washington's gray wolf population last year, wildlife officials report there were fewer conflicts between wolves and livestock or humans in 2013.
The Washington Fish and Wildlife Commission investigated 20 reported attacks on pets and livestock last year. They found that wolves were only involved in four of the attacks.
In 2012, wildlife officials believe wolves killed at least seven cows and one sheep and injured another eight livestock. Most of the attacks were by one pack on one rancher's cattle. Wildlife officials killed seven members of that pack in northeast Washington last year.
Despite the killings, Washington's wildlife agencies reported its annual survey counted 52 of the endangered animals in the state at the end of 2013. That's one more than in 2012.
